Harry Potter?

i think harry potter will die in the next book. i know voldemort will die, but i think that it will be a little weird if harry potter lives, cause he was the "chosen one" does he really have a purpose to live after he kills voldemort? it will be sad but i think he will die. he cant just kill him and then live happily ever after, this isn't a Disney film. he is a hero and sometimes heroes die in there fight.
